They talked about grapefruits, but they didn't mention how grapefruit juice makes pretty much every drug on the planet stronger? It inhibits the CPA-somethingorother enzyme in the liver responsible for breaking down all sorts of drugs, including morphine, other opiods, and antidepressants, making them stay in the body longer.

And the nutmeg thing is true, I've done it. I ingested enough nutmeg to have a psychoactive effect as a kid looking for ways to get high. I did not get high, I got low. Very, very low. Would not recommend.
